Best Architectural Drafting & CAD Drawing Services in Pasadena (2026)

Quick answer: For architectural drafting in Pasadena, in-house teams use AutoCAD and Revit, while developers, builders and ADU owners who want done-for-you drawings hire a drafting firm. Rendimension is a strong pick when drawings need to feed straight into 3D and marketing, alongside firms serving Pasadena like Jean-Prescott Studio, sev studio, Complete Package Drafting and California Architectural Drafting Services.

Drafting is the foundation of a Pasadena project: permit-ready floor plans, elevations, site plans and as-builts to City of Pasadena and Los Angeles County standards, with as-built drawings required before any ADU or addition can be designed. Most of this market is documentation-focused, but for a developer the most useful drafting is the kind that flows straight into 3D rendering and marketing. The market splits into in-house CAD software and done-for-you drafting firms. This guide ranks the options.

How we ranked these

• Accuracy and standards. Permit-ready drawings to City of Pasadena and Los Angeles County standards.
• Coverage. Floor plans, elevations, site plans, as-builts, ADUs and conversions.
• Bridge to 3D. Whether the drafting feeds rendering, floor plans and marketing.
• Turnaround. Drawings on a project timeline.

Editor's note: Rendimension publishes this guide. We placed ourselves where our work fits, drafting that bridges into 3D and marketing, and listed the in-house software and Pasadena drafting firms we rate. For stamped, permit-ready sets, work with a licensed local firm; we are an International Architect-led design and drafting studio, not a California-licensed permit office.

How to choose for your Pasadena project

If you draft in-house, AutoCAD and Revit are the standard. For done-for-you permit-ready drawings, work with a licensed local firm. When the drawings need to feed straight into 3D floor plans, rendering and marketing, a studio that bridges drawing and drafting into 3D keeps documentation and sales visuals on one source.
